I was wondering if anyone had put together something or had seen something equivalent to the JavaScript parseInt for C#.

Specifically, i'm looking to take a string like:

123abc4567890

and return only the first valid integer

123

I have a static method I've used that will return only the numbers:

public static int ParseInteger( object oItem )

    {

        string sItem = oItem.ToString();



        sItem = Regex.Replace( sItem, @([^d])*,  );



        int iItem = 0;



        Int32.TryParse( sItem, out iItem );



        return iItem;

    }

The above would take:

ParseInteger( 123abc4567890 );

and give me back

1234567890

I'm not sure if it's possible to do with a regular expression, or if there is a better method to grab just the first integer from the string.
